The order code defines the B-type sensing element with 6.35 mm overall diameter, a 500 mm straight sensor length, and an accredited (ISO 17025) calibration certificate. STS-100 sensors cover -150 to 650°C, so a single probe can serve both cryogenic bath work and high-temperature dry-block calibration.\u003c\/p\u003e\n\u003cp\u003eInside the Inconel sheath, a pure platinum coil suspended to minimize stress gives near-zero hysteresis, and AMETEK's cleaning and clean-room assembly process keeps impurity-driven drift low even above 350°C. Each probe is annealed and certified, with the certificate checked against the drift between initial and final 0°C measurements. Repeatability is 0.002°C and long-term stability is typically 0.014°C after 100 hours at 650°C. The 6.35 mm diameter leaves room for the sensor-under-test in the same dry-block well while keeping the response fast, and the sensor is intended for use with JOFRA dry-block calibrators, liquid baths and DTI reference indicators.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eWide temperature range of -150 to 650°C\u003c\/li\u003e\n\u003cli\u003e6.35 mm diameter B-type Pt100 sensing element\u003c\/li\u003e\n\u003cli\u003e500 mm straight sensor length\u003c\/li\u003e\n\u003cli\u003eRepeatability of 0.002°C at 0°C\u003c\/li\u003e\n\u003cli\u003eLong-term stability typically 0.014°C after 100 h at 650°C\u003c\/li\u003e\n\u003cli\u003eSpecified low drift for small uncertainty budgets\u003c\/li\u003e\n\u003cli\u003eAccredited ISO 17025 calibration certificate included\u003c\/li\u003e\n\u003cli\u003eFast response for bath and dry-block stability monitoring\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eReference standard for dry-block calibrator verification\u003c\/li\u003e\n\u003cli\u003eTemperature calibration in liquid baths and furnaces\u003c\/li\u003e\n\u003cli\u003eField validation of industrial temperature sensors with JOFRA calibrators\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eAmetek Jofra STS100B500DH Probe Technical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eSensor type\u003c\/td\u003e\n\u003ctd\u003ePt100, 100 ohm at 0°C, alpha 0.00385\/°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTemperature range\u003c\/td\u003e\n\u003ctd\u003e-150 to 650°C (-238 to 1202°F)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSensor diameter\u003c\/td\u003e\n\u003ctd\u003e6.35 mm (0.25 in), B version\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSensor length\u003c\/td\u003e\n\u003ctd\u003e500 mm (19.7 in), straight\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRepeatability\u003c\/td\u003e\n\u003ctd\u003e0.002°C (0.0036°F) at 0°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHysteresis\u003c\/td\u003e\n\u003ctd\u003e0.01°C (0.02°F) at 0°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLong-term stability\u003c\/td\u003e\n\u003ctd\u003eTyp. 0.014°C after 100 h at 650°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSelf-heating effect\u003c\/td\u003e\n\u003ctd\u003e0.06°C\/mW\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResponse time (B, 6.35 mm)\u003c\/td\u003e\n\u003ctd\u003eτ0.5 about 18 s in moving liquid\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMinimum immersion depth\u003c\/td\u003e\n\u003ctd\u003e110 mm (4.3 in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter tube\u003c\/td\u003e\n\u003ctd\u003eInconel 600 sheath\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCable and connection\u003c\/td\u003e\n\u003ctd\u003e4-wire cable with LEMO\/REDEL termination\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCalibration certificate\u003c\/td\u003e\n\u003ctd\u003eAccredited (ISO 17025), H option\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\n\u003cp\u003eManufacturer information: \u003ca href=\"https:\/\/www.ametekcalibration.com\/products\/temperature\/reference-temperature-sensors\/sts-reference-sensors\" target=\"_blank\" rel=\"noopener\"\u003eAMETEK JOFRA STS Series Reference Sensors — ametekcalibration.com\u003c\/a\u003e\u003c\/p\u003e","brand":"Ametek Jofra","offers":[{"title":"Default Title","offer_id":67776345178299,"sku":"IMM_92889783","price":1073.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0777\/2635\/1547\/files\/ametek-jofra-sts100b500dh.jpg?v=1792552914","url":"https:\/\/na.indomultimeter.net\/products\/ametek-jofra-sts100b500dh-probe","provider":"Indo Multimeter","version":"1.0","type":"link"}
